Furthermore, the solidified adhesive continuing to flow back into the reactor will affect the quality of the adhesive inside the reactor. Therefore, further improvements are needed.

The embodiments of this utility model will be described below based on its overall structure.

[0020] Reference Figures 1 to 4 In this embodiment of the present invention, a cooling reflux device for adhesive production includes: a reaction vessel 1 and a motor 4. An air inlet pipe 2 is fixedly connected to one end of the upper part of the reaction vessel 1. A reflux pipe mechanism 3 for refluxing adhesive vapor is provided on one side of the air inlet pipe 2. A cooling chamber 5 for cooling adhesive vapor is provided on one side of the reflux pipe mechanism 3.

[0021] The return pipe mechanism 3 includes a return pipe body 31 located below the motor 4. A threaded rod assembly 32 is rotatably connected to one end of the return pipe body 31. A scraping assembly 33 is provided on one side of the threaded rod assembly 32. A collection hopper 34 is provided at one end of the return pipe body 31.

[0022] The threaded rod assembly 32 includes a threaded rod 321 located at one end below the motor 4, a connecting plate 322 fixedly connected below the threaded rod 321, and a scraper 323 fixedly connected at one end below the connecting plate 322.

[0023] Using the above solution: the rotating scraper 323 can scrape off the adhesive that has solidified on the top of the collection hopper 34, preventing it from accumulating too much and clogging the collection hopper 34.

[0024] The scraping assembly 33 includes a connecting plate 331 screwed to one side of the threaded rod assembly 32. A slider 332 is fixed to one side of the connecting plate 331. A circular scraper 333 is fixed to one lower end of the connecting plate 331. A vent hole 334 is provided at one upper end of the connecting plate 331.

[0025] The collection hopper 34 includes a fixing ring 341 fixed to one end inside the return pipe body 31. A first filter screen 342 is provided on one side of the fixing ring 341. A connecting hopper 343 is fixed to one side of the first filter screen 342. A second filter screen 344 is fixed to one side of the connecting hopper 343.

[0026] Using the above scheme: when the adhesive falls into the collection hopper 34, the viscous adhesive can be directly passed through the first filter screen 342 and continue to flow back. Some solidified adhesive will be scraped into the connecting hopper 343 by the rotation of the scraper 323. The second filter screen 344 can also filter the viscous adhesive so that it can continue to flow back. The solidified adhesive will remain in the collection hopper 34 for collection and processing to prevent it from mixing with other viscous adhesives and affecting the quality of the adhesive.

[0027] The reactor 1 includes a reactor body 11 located below the air inlet pipe 2. A feed valve 12 is provided at one side end of the reactor body 11, a discharge valve 13 is provided at one side end of the reactor body 11, and a support leg 14 is fixedly connected to the lower end of the reactor body 11.

[0028] The cooling chamber 5 includes a cooling chamber body 51 located at one side of the return pipe mechanism 3, an inlet pipe 52 located at one side of the cooling chamber body 51, and an outlet pipe 53 located at one side of the cooling chamber body 51.

[0029] The working principle of this utility model is as follows: Steam in the reactor 1 enters the return pipe body 31 through the inlet pipe 2. When the steam is cooled in the cooling chamber 5, it turns into a viscous adhesive. Some of the adhesive adheres to the inner wall of the return pipe body 31, thus gradually solidifying and preventing the remaining viscous adhesive from flowing back. The motor 4 drives the threaded rod 321 to rotate forward and backward, thereby driving the side-screwed connecting plate 322 and scraper 323 to rotate. When the threaded rod 321 rotates, it drives the side-screwed scraping assembly 33 to move up and down reciprocally. Through the opening on the side of the return pipe body 31... The chute can limit the slider 332. The annular scraper 333 is attached to the inner wall of the return pipe body 31, which can drive the adhesive attached to the inner wall to fall down and finally fall into the collection hopper 34. The viscous adhesive can be directly passed through the first filter screen 342 to continue to flow back. Some solidified adhesive will be scraped into the connecting hopper 343 by the rotation of the scraper 323. The second filter screen 344 can also filter the viscous adhesive so that it can continue to flow back. The solidified adhesive will stay in the collection hopper 34 for collection and processing to prevent it from mixing with other viscous adhesives and affecting the quality of the adhesive.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
